Setup

  1. Unpack: Carefully remove the mattress topper from its vacuum-sealed packaging.
  2. Fluffing: For optimal loft and to allow the fibers to expand, tumble dry the mattress topper on low heat for 20-30 minutes before its first use. Alternatively, lay it flat for a few hours to allow it to naturally fluff up.
  3. Placement: Position the mattress topper on top of your existing mattress. The deep pocket fitted skirt should wrap around the sides and tuck securely underneath your mattress. Ensure all corners are properly fitted for a stable and even surface.

Maintenance

Proper care will ensure the longevity and performance of your Sleep Mantra mattress topper.

  • Washing: The mattress topper is fully machine washable. Use a gentle cycle with cold water.
  • Drying: Tumble dry on low heat. To help maintain its fluffiness and prevent clumping, you may add dryer balls. Ensure it is completely dry before placing it back on the bed.
  • Stain Removal: For spills, wipe immediately with a clean cloth. The water-repellent treatment helps prevent liquids from seeping through.
  • Longevity: Using a fitted sheet over the topper can reduce the frequency of washing, thereby increasing its durability.

Troubleshooting

  • Topper Appears Flat: If the topper seems flat after unpacking, allow it several hours to expand naturally, or tumble dry on low heat for 20-30 minutes to help fluff it up.
  • Topper Shifts on Mattress: Ensure the deep pocket fitted skirt is securely wrapped around all sides and tucked under your mattress. The elasticized design is intended to keep it in place.
  • Reduced Cooling Effect: Ensure your bedding is breathable. Overly thick or non-breathable sheets can counteract the cooling properties of the topper.
